What are the IR Illuminator wavelengths?

IR illuminators work with day/night cameras to provide IR illumination for low light environments and enable you to capture video at night.
IR illuminators are equipped with varying wavelengths—generally from 730 nm to
950 nm. An IR illuminator with a 730 nm wavelength requires a less light sensitive camera and produces a strong, very visible red glow, while an 850 nm wavelength IR illuminator produces a faint visible glow, making it semi-covert. An IR illuminator with a 940 nm wavelength produces a glow that is virtually invisible to the human eye, which makes it an ideal choice for most covert applications. A 940 nm illuminator must be used with a very light sensitive camera with no IR cut filter, or if the camera does have an IR filter, it has to be removed for optimal results.
